DETAILED DESCRIPTION OF TABLE INVENTION
The following description is of the best-contemplated mode of
carrying out the invention. This description is made for the
purpose of illustrating the general principles of the invention and
should not be taken in a limiting sense. The scope of the invention
is best determined by reference to the appended claims.
First Embodiment
Referring to FIG. 2, a first embodiment of a display 10 comprises a
base 20, a body 30, an elastomer 202, a revolving shaft 40, and two
elastic elements 50. The base 20 comprises a frame 201. The body 30
is rotatably connected with a frame 201 in such a manner that the
body 30 can move between a rotatable position (first position, as
shown in FIG. 3) and an engaged position (second position, as shown
in FIG. 4). The elastomer 202 and the elastic elements 50 are
disposed on the frame 201.
The body 30 comprises a gear element 301. The gear element 301
comprises a plurality of first protrusions 301a and a plurality of
first notches 301b. The frame 201 of the base 20 comprises a
receiving part 2011, two fixed elements 2012, two movable pins
2013, and two openings 2014. The receiving part 2011 comprises a
curved edge 2011a. The elastomer 202 and the fixed elements 2012
are disposed in the curved edge 2011a. The elastomer 202 abuts
against the gear element 301. The fixed elements 2012 are connected
with the elastic elements 50. The movable pins 2013 are moved
between an original position (third position, as shown in FIG. 3)
and a proceeding position (fourth position, as shown in FIG. 4),
and are exposed outside the openings 2014.
The elastomer 202 further comprises a plurality of second
protrusions 202a and a plurality of second notches 202b, as shown
in FIG. 3. Additionally, referring to FIG. 2, the revolving shaft
40 passes through the gear element 301 and the center of the frame
201. Thus, when the body 30 rotates, the gear element 301 of the
body 30 rotates relatively around the revolving shaft 40.
Referring to FIG. 3, when the body 30 is in the first position and
the movable pins 2013 are in the third position, the second
protrusions 202a are compressed by the first protrusions 301a and
the second notches 202b are opposite to the first notches 301b,
furthermore, the body 30 can freely rotate to adjust the angle.
When the body 30 has been rotated to the second position and the
movable pins 2013 are still in the third position, the body 30
still can rotate to adjust the angle.
Referring to FIG. 4, when the body 30 has been rotated to the
needed angle, the body 30 is in the second position. Furthermore,
the movable pins 2013 are moved to the fourth position from the
third position. At that time, the second protrusions 202a and the
movable pins 2013 are engaged with the second notches 202b. Thus,
the body 30 is fixed in the position after adjustment. When the
body 30 is moved to the first position from the second position,
the elastic elements 50 connected with the movable pins 2013 can
return the movable pins 2013 back to the third position.
Referring to FIG. 3 again, when the display 10 is not used, the
body 30 is in the first position and the movable pins 2013 are in
the third position. When the angle of the display 10 is adjusted,
the body 30 is rotated to the needed angle and the body 30 is moved
to the second position from the first position, thus, the second
protrusions 202a are engaged with the second notches 202b. The
movable pins 2013 are subsequently moved to the fourth position so
that the movable pins 2013 are engaged with the second notches
202b. Consequently, the body 30 can be fixed at a particular
angle.
Note that the gear element 301 and the body 30 can be integrally
formed, but can also be disposed on the body 30 by melting and
screws. Further, it is noted that the number of the first
protrusions 301a, the first notches 301b, the second protrusions
202a and the second notches 202b are not limited to those depicted
in FIG. 2 and FIG. 4, which can be increased or reduced depending
on requirements.
In conclusion, the display 10 of the first embodiment provides a
gear element 301 and the special design of the frame 201, which is
convenient for user to adjust the angle of the display 10.
Furthermore, when the number of the first protrusions 301a and the
second protrusions 202a is greater, the required angle can be more
accurate.
Second Embodiment
Referring to FIG. 5, a second embodiment of a display 100 comprises
a base 200, a body 300, an adjusting element 3001, an elastomer
2002, and two movable pins 400. The adjusting element 3001 is
disposed on the body 300. The base 200 comprises a frame 2001. The
frame 2001 is connected with the adjusting element 3001. The
elastomer 2002 is disposed in the frame 2001 and abuts the
adjusting element 3001. The movable pins 400 are movably disposed
on the frame 2001 in such a manner that the movable pins 400 are
moved between a separated position (first position, as shown in
FIG. 6) and an engaged position (second position, as shown in FIG.
7).
Referring to FIG. 5, the frame 2001 comprises two first elastic
elements 20011, two fixed elements 20012, and two openings 20013.
The first elastic elements 20011 are respectively connected with
the movable pins 400. The fixed elements 20012 are connected with
the first elastic elements 20011 and the movable pins 400 are
respectively disposed in the openings 20013.
Referring to FIG. 6, the adjusting element 3001 comprises a
plurality of orientated elements 30011, a plurality of second
elastic elements 30012, and a plurality of openings 30013. The
orientated elements 30011, which comprise a first inclined plane
30011a, are respectively disposed in the openings 30013 and are
exposed outside the openings 30013. The second elastic elements
30012 are respectively connected with the orientated elements
30011. Furthermore, each movable pin 400 comprises a button 4001
and a notch 4002. The button 4001 can easily move the movable pin
400. Referring to FIG. 8, one of the notches 4002 is disposed
opposite one of the orientated elements 30011, and each notch 4002
comprises a second inclined plane 4002a.
Referring to FIG. 6 and FIG. 8, when the movable pins 400 are in
the first position, the orientated elements 30011 of the adjusting
elements 3001 are separated from the notches 4002 of the movable
pins 400 so that the body 300 can freely rotate. At the same time,
the second elastic elements 30012, which are connected with the
orientated elements 30011, are compressed. Referring to FIG. 7 and
FIG. 9, when the movable pins 400 are moved to the second position,
the orientated elements 30011 of the adjusting elements 3001 are
moved upward by the elastic force provided by the second elastic
elements 30012 and the orientated elements 30011 are then engaged
with the notches 4002 of the movable pins 400, thus, the first
inclined planes 30011a of the orientated elements 30011
respectively abut the second inclined planes 4002a of the notches
4002 and the first elastic elements 20011 are extended. When the
movable pins 400 leave from the second position, the notches 4002
of the movable pins 400 and the orientated elements 30011 are
separated, and the movable pins 400 return to the first position by
elastic force of the first elastic elements 20011.
When the display 100 is used, the body 300 is moved to required
angle, thus, the adjusting elements 3001 and the frame 2001 are
relatively rotated. The elastomer 2002 can aid in the rotation and
the orientation of the body 300. When the movable pins 400 are in
the first position, the orientated elements 30011 of the adjusting
elements 3001 are separated from the notches 4002 of the movable
pins 400. When the body 300 is rotated positioning the notches 4002
of the movable pins 400 opposite to the orientated elements 30011,
the movable pins 400 are moved to the second position so that the
second inclined planes 4002a of the notches 4002 are respectively
engaged with the first inclined planes 30011a of the orientated
elements 30011. Thus, the body 300 is fixed at the particular
angle. At the same time, the first elastic elements 20011 connected
with the movable pins 400 can be extended. When rotating the body
300 to another angle, the movable pins 400 are pulled toward the
inverse direction of the orientated elements 30011, and the
inclined force from the second inclined planes 4002a pushes the
first inclined planes 30011a so that the orientated elements 30011
are pushed downward. Thus, the second elastic elements 30012, which
are connected to the orientated elements 3001, are compressed. At
the same time, the notches 4002 of the movable pins 400 are
separated from the orientated elements 30011. Additionally, the
movable pins 400 can return to the first position by the elastic
force of the first elastic elements 20011. The display 100 further
comprises a revolving shaft 500, which passes through the adjusting
elements 3002 and the center of the frame 2001, thus, the adjusting
elements 3002 can be rotated around the revolving shaft 500.
In conclusion, in the second embodiment of the display 100, the
inclined angle can be more easily adjusted by the user, and the
elastic elements are used to automatic orientation. Thus, the
invention is more useful than the hinge of a conventional
display.
Note that the first elastic elements 20011 and the second elastic
elements 30012 are compression springs. Furthermore, note that the
adjusting elements 3001 are disposed on the body 300 by melting or
screws, or can be integrally formed with the body 300.
While the invention has been described by way of example and in
terms of the preferred embodiments, it is to be understood that the
invention is not limited to the disclosed embodiments. To the
contrary, it is intended to cover various modifications and similar
arrangements (as would be apparent to those skilled in the art).
Therefore, the scope of the appended claims should be accorded the
broadest interpretation so as to encompass all such modifications
and similar arrangements.
